Laporan Penelitian Unggulan Perguruan Tinggi : Pemanfaatan Rain Harvesting sebagai Energi Listrik
No full textEnergi minyak bumi di Indonesia mengalami penurunan cadangan energi sebesar
1,2% dari tahun sebelumnya. Penurunan ini disebabkan oleh banyaknya masyarakat yang
menggunakan energi minyak bumi dibanding energi yang lain. Cadangan minyak Indonesia
diperkirakan tinggal 3,7 miliar barel pada tahun 2015 dan akan habis dalam waktu kurang
dari 20 tahun lagi. Bila dibagi dengan rata-rata produksi minyak Indonesia yang sekarang 300
juta barel per tahun, cadangan minyak itu habis dalam 12 tahun.
Rain Harvesting atau pemanenan air hujan adalah kegiatan menampung air hujan
secara lokal dan menyimpannya melalui berbagai teknologi, untuk penggunaan masa depan
untuk masa depan dalam memenuhi tuntutan konsumsi atau kegiatan manusia.
Teknologi Rain Harvesting ini dapat menyimpan air hujan dalam jumlah banyak dan
mengubahnya menjadi energi listrik. Dengan adanya teknologi Rain Harvesting diharapkan
dapat membantu kegiatan manusia dalam bidang energi dan memperpanjang waktu habis
energi minyak bumi.
Air hujan yang telah ditampung di dalam tandon dialirkan sehingga membentuk
suatu aliran air. Aliran air inilah yang dimanfaatkan untuk menggerakkan turbin karena air
akan menggerakkan sudu-sudu kincir air sehingga membuat kincir air menjadi berputar.
Kincir air ini terhubung secara langsung dengan generator, sehingga bila kincir air bergerak,
maka secara otomatis generator juga akan ikut bergerak. Selama bergerak berputar, generator
ini akan menghasilkan energi listrik

Herbal medicine is believed to provide a number of health benefits as well as to treat various diseases. Traditional spices are quite effective in maintaining endurance and are one of the solutions against the increasingly aggressive coronavirus (Covid-19) outbreak. Ginger drink is one of the traditional drinks that is easy to make and has the power to increase endurance to avoid the coronavirus (Covid-19). Ginger contains the bioactive compound gingerol which can fight the respiratory syncytial virus that causes respiratory infections. To make the ginger drink, it is necessary to squeeze ginger from the dregs. So far, the processing is done manually by using a grate and squeezing it by hand. People who grate get tired, especially if they have to grate large amounts of ginger. Based on this, appropriate technological innovations need to be applied to increase production yield and quality of squeezed ginger, namely by making the design of "Automatic Ginger Squeezing Machine" which is quite practical and can be used on a household scale with a capacity of 35 kg/hour and a power of 750 Watts. Ginger that is processed in this machine will be immediately separated from the pulp. The production process will be shorter and more efficient because the ginger juice and pulp are separated automatically with a larger capacity. This machine uses stainless steel to ensure the quality of the processed product and maintain the health of the process. This machine works automatically from the beginning to the end of the ginger pressing process
